This image shows an engineering drawing and specifications document from Coldzone for a commercial refrigeration system, including an engineering summary table and electrical defrost wiring diagram (ED-26) for a facility in Illinois. The engineering summary details multiple cooler units (produce cooler, milk/dairy cooler, food prep cooler, and others) with specifications for each unit including model numbers AK2B-108B from Coldzone, operating at 460V/3PH/60HZ with connected loads ranging from 37.30 amps.

The technical specifications include detailed wiring requirements, with the electrical defrost system being factory-wired and requiring field wiring by electrical contractors. The document includes specific installation notes regarding temperature, water and head pressure controls, and insulation requirements. The system appears to be part of a larger retrofit project for the Treatment and Detention Facility's dietary unit, with detailed specifications for contractor responsibilities including pressure testing, refrigerant charging, and control panel installation.
